Now that I know the details - I don' think this is going to work. Not  
with 100 TB of data. It kind-of-works with 1 TB.
Can anybody comment on the feasibility of rsync on 1 million files?
Maybe DRBD would be a solution.
If you can retrofit DRDB to an existing setup...

If not it's faster to move the drives physically - believe me, this  
will create far less problems.
In a SAN, you would have the possibility of synching the data outside  
of the filesystem, during normal operations.


100 TB is a lot of data.
How do you back that up, BTW?
What is your estimated time to restore it from the medium you  back  
it up to?



cheers,
Rainer
